test(bdd): add successful command step

[sbaum1994]

TL;DR

Adds line and docstring forms of When I successfully run command, removing mechanical exit-zero assertions while keeping the command and its meaningful inputs visible.

Additional Details

• Preserves the resolved command, exit result, stdout, stderr, interpolation, and command logging.
• Seeds the existing successful-command cache only after exit code 0.
• Migrates the control observability install and collector readback. Negative resource checks keep their explicit exit-code assertions.
• Updates the BDD guidance and DSL catalog with the common-operation abstraction criteria.

Customer release notes: Not customer visible.

Plan summary: Not applicable.

Dependencies: None. No license or NOTICE changes.

Related Pull Request: #866

For the Reviewer

Please focus on the cache and result-preservation behavior in steps/command_steps.go and whether the migrated Gherkin keeps the operator action clear.

For QA

Passed:

• go test -short ./... from tests/bdd
• tests/bdd/scripts/lint.sh
• BDD_CLEANUP_MODE=stack-single go test -timeout 30m -run '^TestObservabilityControl$' -count=1 -v . against an isolated k3d-ncp-local kubeconfig (1 scenario and 29 steps passed in 11m18s)

The first live attempt encountered a transient NGC 403 for one chart. A direct authenticated pull succeeded, and the final clean-stack rerun passed.

QA needed: No separate QA.

📝 Walkthrough

Walkthrough

The BDD DSL adds line-based and docstring-based successfully run command steps. These steps require exit code 0, preserve results, resolve variables, log execution, and cache successful commands. Existing scenarios and tests now use and validate the new steps.

Changes

BDD successful command flow

Layer / File(s)	Summary
DSL contract and contributor guidance tests/bdd/PLAN.md	Documents successful-command steps, result preservation, interpolation, logging, and successful-command caching.
Successful command execution tests/bdd/steps/command_steps.go, tests/bdd/steps/context.go	Registers line-based and docstring steps. Executes commands through runSuccessfully, requires exit code 0, records results, and documents cache behavior.
Scenario adoption and validation tests/bdd/features/observability-control.feature, tests/bdd/steps/steps_test.go	Migrates suitable feature steps and tests interpolation, result recording, output preservation, non-zero exits, and caching.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 4ffd1

This change adds a successful-command BDD step and updates its usage without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.

Remove the redundant forwarding handlers.

Register the line form with sc.runSuccessfully and use an inline adapter for doc.Content. TestRegisterAllRunsAFeatureFile already covers both forms with Godog v0.15.1.
